A gravimetric factor converts grams of a compound into grams of a single element. For example, we'll find the gravimetric factor of Cl in AgCl.
Use the Atomic Mass of Ag(107.868) and the atomic mass of Cl(35.453) and add them together to get 143.3. Then divide 35.453 by 143.3 to get .2474.
.2474 is the gravimetric factor of Cl in AgCl.

What distinguishes gravimetric anlaysis from other forms of analysis?
Gravimetric analysis measures the mass of a substance to determine its quantity, while other forms of analysis may involve measuring other properties such as volume or concentration. Gravimetric analysis typically provides more accurate results because it directly measures the amount of the target substance, and it is often used for determining the purity of a sample or detecting trace amounts of a substance. The main limitation of gravimetric analysis is that it is time-consuming and may require complex procedures compared to other analytical methods.
What are the requirements for a successful gravimetric analysis?
The steps commonly followed in gravimetric analysis are (1) preparation of a solution containing a known weight of the sample, (2) separation of the desired constituent, (3) weighing the isolated constituent, and (4) computation of the amount of the particular constituent in the sample from the observed weight of the isolated substance.
Types of precipitation in gravimetric analysis?
In analytical chemistry, gravimetric analysis is used to determine an analyte, which is based on the mass of a solid. The types of precipitation in gravimetric analysis are pure precipitation.
Why digestion is necessary in gravimetric titration?
Digestion is necessary in gravimetric titration to ensure complete and uniform precipitation of the solution being analyzed, allowing for accurate measurement of the precipitate. Digestion also helps in converting the analyte into a form suitable for precipitation, and aids in the formation of a crystalline precipitate which can be easily filtered and weighed.
What is gravimetric finish?
Gravimetric finish refers to a method used in analytical chemistry to quantitatively determine the concentration of a substance in a sample based on the mass of a precipitate formed during a chemical reaction. This technique involves measuring the mass of the solid residue after a series of chemical reactions take place, allowing for precise quantification of the original substance in the sample.
Why do we multiply the mass of precipitate with a gravimetric factor?
The gravimetric factor is related to the percentage of element (or ion) to be determined in the precipitate (as compound).
Why does solubility play a role in a gravimetric analysis?
Solubility always has to be considered as a source of error in gravimetric analysis because what remains in solution, no matter how little, doesn't get measured (although, it can sometimes be determined indirectly). So, gravimetric results are always erroneously low due to this factor.
What is digestion in gravimetric analysis?
gravimetric analysis is the study of weighing certain compounds, comparing, heating, precipitating, to give us the mass of a specific molecule as a result gravimetric analysis is the study of weighing certain compounds, comparing, heating, precipitating, to give us the mass of a specific molecule as a result

What is gravimetric induction?
Gravimetric induction is a process in which a mass is induced to move within a gravitational field due to the application of external forces or influences. This can occur in various situations, such as a pendulum swinging back and forth due to gravity's pull, or a satellite orbiting a planet under the influence of gravitational forces.
